Belajar Security Architect - Vendor & Technology Selection

#Pendahuluan

Setelah di episode 14 kita mempelajari security metrics & board reporting, pada episode ini kita dalami vendor & technology selection — bagaimana memilih tools keamanan yang tepat, kapan harus build vs buy, dan mengelola risiko vendor. Keputusan technology yang salah bisa menghabiskan jutaan dolar dan meninggalkan security gap.

Mengapa vendor selection penting? Karena security tooling bukan commodity — pilihan yang salah bisa menciptakan blind spots, integration nightmares, dan vendor lock-in yang menyakitkan.

#Evaluation Framework

#Weighted Scoring Model

Criteria	Weight	Score (1-5)	Weighted
Security features	30%	?	?
Integration capability	20%	?	?
Ease of use	15%	?	?
Total cost of ownership	15%	?	?
Vendor stability	10%	?	?
Support quality	10%	?	?

#Evaluation Process

100%

#Build vs Buy

Factor	Build	Buy
Control	Full control	Vendor-dependent
Cost	Dev time + maintenance	License cost
Time to value	Longer	Shorter
Customization	Unlimited	Limited
Maintenance	Your team	Vendor

#Decision Framework

Kriteria	Build	Buy
Core competency	Yes, it's our differentiator	No, commodity function
Time critical	No, we have time	Yes, need it now
Unique requirements	Yes, very specific	No, standard needs
Maintenance capacity	Yes, we can maintain	No, lean team

Tip

Build untuk core competency, buy untuk commodity. Kalian tidak perlu build SIEM dari nol — tapi kalian mungkin perlu build custom detection rules yang spesifik.

#Vendor Risk Management

#Third-Party Risk Assessment

Area	Pertanyaan
Security	Bagaimana vendor mengamankan produknya?
Compliance	Apa compliance yang dimiliki vendor?
Financial	Apakah vendor stabil secara finansial?
Operational	Bagaimana SLA dan support quality?
Contractual	Apa termination clause?

#Vendor Risk Scorecard

Criteria	Weight	Assessment
Security posture	30%	Security audit report
Compliance	20%	SOC2, ISO certification
Financial stability	15%	Revenue, funding, market position
Operational resilience	15%	SLA, uptime history
Contract terms	10%	Flexibility, exit terms
Reference check	10%	Customer feedback

Warning

Vendor risk assessment bukan sekadar checklist — ini investment due diligence. Breach yang melibatkan vendor supply chain (seperti SolarWinds) menunjukkan pentingnya vendor risk management yang ketat.

#POC (Proof of Concept)

#POC Planning

Phase	Duration	Activities
Preparation	1 week	Requirements, success criteria
Deployment	1-2 weeks	Install, configure
Testing	2-4 weeks	Execute test cases
Evaluation	1 week	Score, compare, decide

#POC Success Criteria

POC success criteria template

□ Meets all must-have requirements
□ Integration with existing stack works
□ Performance acceptable for our scale
□ Team can operate without vendor support
□ Total cost within budget
□ Security audit passed

Note

POC harus memiliki success criteria yang jelas dan terukur sebelum dimulai. Tanpa criteria, POC menjadi "feel-based" yang bisa dimanipulasi oleh vendor sales pitch.

#Penutup

Inti yang harus dibawa pulang:

Evaluation framework: weighted scoring dengan criteria jelas.
Build vs buy: build core competency, buy commodity.
Vendor risk: security, compliance, financial, operational, contractual.
POC: define success criteria sebelum mulai.

Di episode 16 selanjutnya kita akan membahas security operations architecture — SOC design, SIEM/SOAR, dan detection architecture.
